Mileage and capacity oddity from my 2023 M3LR sticker?

[mapman]

Picked mine up yesterday!

The Mulroney sticker claims 358 miles of range, and 26 kW-hr (combined) per hundred miles. That would seem to imply a 93 kWh battery pack. Are the packs really that large, or am I missing something?

Congrats! Definitely not a 93kWh pack. Maybe it's factoring regenerative braking.

Doesn't the Monroney state the pack size too?

I would certainly be surprised if it was that large. No, the sticker doesn't report battery capacity. Just MPGe, range, and estimated charge time (8.5 hours, 240v).

It also has a QR code that points to the fueleconomy.gov page for the 2018 model...

I believe the EPA rated range is about 234 wh per mile. So 358 miles would be 83,772 wh... it's probably an 82kWh pack.

The energy graph in your car will show you the energy consumption of the rated range... it's the solid line, while your consumption is the dashed line.

And you *can* get rated range, but not always. You can even get quite a bit better than rated range, but only under the right conditions.

You can also get way worse than rated range, which is usually a lot more fun.

Packs are all 79-82kWh with recent models being in the 80-81kWh range.

Listen to your @father_of_6. EPA range is half city / half highway so there's lots of regen.
